Page_Load question

I know the syntax is correct because I use it elsewhere. However, I am getting the following error (please see attached) with Page_Load: 'Protected Sub Page_Load....has multiple definitions with identical signatures'.

Does this mean I can only have one 'Protected Sub Page_Load' per aspx file? And what would I replace it with?

Move the username.Focus() code to the page load routing you are keeping.

Within the subroutine, you need to determine where you want that code to run. It can be the first, last line or anywhere in that block of code since Focus() isn't related to anything else in that block.
